This visualization is quite similar to the task completion spreadsheet – you just display issues instead of tasks. Repeated observations are highlighted in different colors – the more colorful an issue, the more important to fix it.

Summing up

Finding the low hanging fruit in your list of usability issues isn’t that hard. While some issues are just obvious to spot during testing, others may only become visible, after you have taken a closer look at your data.

The above methods show when a problem actually is a problem, especially if you are responsible for communicating these insights to the rest of your team.

How do you decide which usability issues to tackle first? I’ll be happy to hear about your workflows.
